FIELD: electricity.
SUBSTANCE: tap changer with semiconductor switching elements is intended for uninterrupted changing between winding taps of a step transformer; it is made as a hybrid switch comprising fixed mechanical contact fingers and opposed contacts installed at a movable contact bracket. Semiconductor switchover units are intended for load transfer, they are switched by means of contacts at the contact bracket when load is transferred in a specified switching sequence.
EFFECT: development of the tap changer featured by the simple design and high operational reliability, which can be used for switching of different step transformers without forced special-purpose matching to the transformer.
